Value Collection 144429603170000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603170000 is a straight-flute chucking reamer designed to finish-ream precision holes to a diameter of 0.3170 inches. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent bore accuracy in both manual and CNC drilling applications. The straight-cylindrical shank seats securely in standard drill chucks and collets. With six flutes and a right-hand cutting direction, it removes material evenly and produces a smooth, true bore surface. Machinists and toolroom professionals use this reamer as a finishing step after drilling to bring holes to tight dimensional tolerances.

This chucking reamer is suited for general-purpose reaming operations in machine shops, toolrooms, and production environments. The 0.3170-inch diameter falls within the 0.3000 to 0.3499 inch decimal-inch range, making it appropriate for finishing bored or drilled holes where close tolerances and smooth finishes are required. The HSS construction handles a range of workpiece materials including mild steel, aluminum, brass, and plastics under standard cutting speeds and lubrication conditions.

Key Features

• 0.3170-inch finished bore diameter for precision hole sizing
• High-speed steel (HSS) construction for durability across common workpiece materials
• Six straight flutes for even material removal and smooth bore finish
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank fits standard drill chucks and collets
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a standard drill chuck or collet that accepts a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by machinists and toolroom professionals. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and verify runout is within acceptable limits. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill the hole to near final size before reaming — never use a reamer to remove excessive stock.
